I really like the perspective of this game, looking up at the human from the arcade machine immediately made me think of Wreck it Ralph. As far as a rhythm game goes, this one is playable but it's missing parts to make it great. One thing, as noted in Phive's comment, is some the feedback when hitting the buttons. The lights are alright but there were some moments where I wasn't sure if I was hitting anything at all. Overall though I think you have a good concept here and I'd love to see it developed further!
